<p>A self sealing vessel assembly for high pressure microwave assisted chemistry is disclosed. The vessel assembly includes a polymeric cylinder (12) and a circular polymeric cap (13) for the cylinder, the cylinder being closed at one end and open at the other end to receive the cap. The open end of the cylinder has a lip that is bevelled inwardly from the open end, and the circular polymeric cap (13) has a bevelled lower edge that engages the bevelled lip when the cap (13) is placed upon the polymeric cylinder (12). For high pressure applications, a choke cylinder depends from the bevelled lower edge of the cap, and has an outer diameter substantially the same as the inner diameter of the polymeric cylinder (12) so that the choke provides a self sealing mechanism for the cylinder as pressure from a chemical reaction increases within the cylinder. A supporting frame (14) extends along the cylinder (12) and across the lid (13) and across the closed end of the cylinder, and prevents the lid from being displaced from the cylinder when pressure is generated inside of the vessel. <IMAGE></p> |
